About

In 2022, I set out on the challenge of joining one of the most prestigious colleges in Brazil. That journey shaped me, but it doesn’t define me entirely.

Alongside being an engineering student at ITA, I’ve been president of the school band, worked as a field software engineer at VTEX, competed in hackathons, volunteered for three years at a prep school for low-income students, and built LLM-powered products at Selvia AI Medical Accounting.

Today I’m a Software Engineer at SumUp, shipping production features in Elixir and Go while deepening my understanding of distributed systems and observability.

Outside of work, I enjoy cooking, playing roguelike games, and trying to finally beat Super Meat Boy.

Technologies I work with:

Elixir
Go
TypeScript
Python
Kotlin
React / Next.js
AWS (Lambda, SQS, SNS)
OpenTelemetry
LangGraph
SQL / MongoDB
JavaScript (ES6+)
Node.js
